INVESTIGATION OF DETERIORATION PROCESS OF ORGANIC COATING USING 1-DIMENTION SOM NETWORK COMBINED WITH EIS
|
Abstract:
In this paper,the EIS characteristic of organic coatings tested under cyclic wet-dry conditions was analyzed.The changing rate of impedance was selected as the training sample for 1-Dimention SOM(Self-Organizing Feature Map) neural network.Each sample corresponds to a certain activation level of the neuron in the output layer.According to the speciality of 1-D SOM network,the changing trend of the activation level can generally reflected the coating degradation process.Combined with the characteristic of EI...
